tse (Triple speed ethernet) and SGDMA (Scatter Gather DMA) do not seem fully connecte

So I've searched, and nothing seems to quite fit my case. I am using SGDMA and TSE with InterNiche Portable TCp/IP v3.1 and Simple Socket Server demo and Altera 10.0 (or very close, maybe 10.1)...

You can check with the debugger that the DMA driver function is called properly.

Check also that the SGDMA is connected to the memory buffer it is supposed to write the packet to in SOPC builder.

I think it's easier to debug the SGDMA with signaltap. At least you see what it is trying to do and can have an idea of why the packet contents isn't read.
